Maintenance
For proper ventilation, use the following instructions to maintain the fan filter and fan. For information about the operating temperature range, refer to Specifications on page 20.
FAN FILTER: CLEANING OR REPLACING
Filters can be cleaned and reused, or they can be replaced. The fan filter should be removed and cleaned as required to ensure proper ventilation and cooling of the unit. A clogged fan filter or an ambient operating temperature exceeding 95°F (35°C) will cause the unit’s internal temperature to rise above the specified temperature range. When this happens, the Pelco badge LED will flash and an alarm will sound indicating there is an alarm condition; however, the fan’s LED indicator will not glow red. If this occurs, replace the fan filter next to the alarm indicator.
